-------------------------------------
    Resolution: Cannot Reproduce

We're not going to clamp our MTU to help with broken ISPs and issues with path discovery at this time. Thanks for reporting this, though. We'll re-evaluate if it becomes a larger scale problem.

> That's a problem, because most browsers don't failback to IPv4 if the IPv6 TCP session is properly established but hang forever. Currently, all IPv6 enabled browsers can't access to anything hosted on 2a01:4f8:130:2192::2 at all
